Q 5 oiaim's'. (c1. i20--69) The invention relates to bottles and an object of the same is to provide a bottle having a reservoir or chamber in the neck thereof which is automatically filled with the liduid contained in the bottle so that'a' small supply 7 will be available for convenient use.

A further object of the invention is to provide a bottle of this character wherein the insertion of the stopper or closure serves to 'displace some of the air in the bottle so that upon removable of the stopper or closure thedisplaced air will elevate a quantityof the liquid'into the reservoir or chamber; v i

The invention further contemplates an ink bottle having a chamber or reservoir in the neck thereof which is automatically filled with 'ink upon removal of the stopper so thata fountain pen may be inserted into the neck 'for refilling and thereby eliminatethe necessity of inserting the pen directly into the bottle.

With the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangements of parts and operations to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein:

Figure 1 is a vertical sectional view of an ink bottle constructed in accordance with my invention;

Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1;

Fig. 3 is a modified embodiment of the ink bottle;

Fig. 4 is a vertical sectional view of a second modification of the invention;

Fig. 5 is a vertical sectional view of a bottle wherein all of the parts are formed as a unitary structure; and

Fig. 6 is a slight variation of the device disclosed in Fig. 1;

Referring to the embodiment of the invention disclosed in Figs. 1 and 2 an ink bottle 5 having a neck 6 for the reception of the usual stopper '7 is provided. Formed on the walls of the neck 6 at its lower end is an annular shoulder 8 and resting thereon is a gasket 9 formed of rubber or other yieldable material and which has its upper face spaced slightly from the under face of the stopper '7.

A reservoir or auxiliary chamber 10 preferably formed from glass and shaped to conform to the pen nib carrying end of a fountain pen extends centrally through the washer 9 and depends into the ink bottle 5. The washer 9 tightly hugs the walls of the reservoir or chamber 10 to effect an air seal around the same. An annular flange 11 is formed on the upper end of the chamber 10 and abuts the upper face of the washer 9-to prevent downward displacement of the auxiliary chamber.

The lower end of the chamber 10 terminates in a vertically extending conduit 12 whose lower end lies' close to the bottom of the receptacle 5.

In the operation of the invention the insertion of 'the stoppe'r into the neck causesth'e air to be displaced therefrom and a consequental displacement of air in the bottle 5. As the stopper is removed an amount of liquid equal in volume to thedisplaced air is forced upwardly through the conduit 12 and into the chamber or reservoir 10. The fountain 'pen canthen be inserted into the chamber. or, reservoir,l0 for refilling withoutlthe disadvantage of l soiling the barrel 'of the. pen. li/loreover the pen may be'refilled with facility asitis'only necessary to remove the stopper 7 from' the neck 6.

In the form of the invention disclosed in Fig. 3 an auxiliary reservoir 13 is snugly received within the neck 6 and terminates in a tapered lower end portion 14 which lies below the neck and which is formed with the vertically extending conduit 15. The upper end of the auxiliary chamber is provided with an annular flange 16 which rests upon a gasket 17 surrounding the chamber 13. In this instance the stopper 7a is received in the upper portion of the auxiliary chamber.

With the construction disclosed in Fig. 4 a washer 18 rests upon an annular flange or shoulder 19 formed upon the interior of the neck at its lower end. A relatively long conduit 20 depends from the center of the washer and has its lower end extending in close proximity to the bottom of the bottle. The upper end of the conduit opens into the neck of the bottle so that the latter constitutes a reservoir or chamber. A stopper 21 is normally received within the neck and is of a length to contact with the upper face of the Washer as disclosed in Fig. 4.

In the construction disclosed in Fig. 5 the parts are shown as a unitary structure. In this instance an inverted cone-shaped chamber or reservoir 34 has its walls integrally joined with the lower end of the bottle neck as indicated at 35. The lower end of the chamber or reservoir is formed with a vertically extending tube 36 which extends within the bottle. The neck is normally closed by a stopper 37. In practice this form of bottle is filled from the side and after which it is sealed as at 38.

In Fig. 6 a bottle is illustrated which is a slight variation from Fig. 1. In this embodiment of the invention a tube 39 extends centrally within the bottle 40 with its upper end extending within the neck of the bottle. An annular flange 41 is formed with the tube slightly below its upper end and rests upon the annular flange 42 formed at the lower end of the neck. A washer 43 is received on the upper end of the tube and has its upper face flush with such upper end. As in the construction disclosed in Fig. 1 this form of the invention includes a stopper 44 which is normally received in the neck and abuts the upper face of the washer 43.

What is claimed is:

1. A liquid dispensing device comprising a container having an opening in the upper end thereof, a chamber located within the container adjacent the open upper end thereof, a tubular member connecting said chamber with said container adjacent the bottom of the latter, and a cap for the open' end of the container having a piston-like portion fitting into the chamber for building up a pressure in the container above the liquid therein tending to force the liquid into the chamber whereby removal of the piston-like portion aforesaid from the chamber causes a quantity of the liquid in the container to flow into said chamber.

2. In a device of the class described, a container for liquids provided with means constituting a chamber at the mouth thereof, said chamber being located above the normal level of the liquid in said container and having a portion adapted to receive a closure member, a tube connecting said chamber with said container below the normal liquid level in the latter, and a piston-like closure member engageable with the aforesaid portion of said chamber to provide a stopper for the container and for forcing air into said chamber to close the container and for forcing air into said container when said closure is applied, for the purpose set forth.

4. In a device of the class described, a bottle having means forming a chamber in the neck thereof, said chamber being located above the normal liquid level of the bottle and having a portion adapted to receive a stopper, a tubular member connecting said chamber with said bottle below the normal liquid level in the latter, and a stopper constituting a closure member insertable in said chamber to close said bottle and to force air into said bottle, for the purpose set forth. 7

5. The combination with a liquid container, having an opening, of means forming a reservoir of smaller capacity associated with said container at the opening thereof and sealing the same, a feed tube of relatively small bore connected to said reservoir and extending into said container to apoint adjacent the bottom thereof, and a piston-like closure member frictionally engageablein said reservoir to close said container and for forcing air from said reservoir through said feed tube into said container, for the purpose set forth.
